What have I learnt by this habit of posting daily?

Notice I call it a habit not a goal anymore. Doing the same thing for
this long had made it a habit. So what have I learnt from this.

Show up
Yes everyday I showed up. Took the laptop out and just started. Never
new in advance what I will write but just began. This created the
posts that you all are reading and hopefully gaining something.

So start showing up to whatever goal you have setup. If your aim is to
get good marks, then show up and stick to your routine. If you aim is
to learn catia, ansys etc. show up. Switch on the software and begin
tinkering. If you want a productive training, then show up everyday,
consistently.

Showing up is so simple yet how few times we use it. I have been
blogging on this blog since 2004 and this is the first year that I
have really taken an extra effort to be consitent in posting. So it
was big lesson for me.

As I said earlier, since lot of travel is involved in October, so
posting rate might suffer. But rest assured that I will be writing
everyday and posts will flash only when I have the opportunity to
connect to the Internet.

Revision technique to boost your studies

Today learnt a great revision technique from one of my teammate in
office.

We are all attending 5 days training on some new technology and today
was the second day. Yesterday, we began at 8 and finished at 5 with
some good topics and hands on. Today morning he entered and he took
out a sheet of paper and rerun all the things that we did last day.

So how can you apply it in studying for aesi.

Take a paper, and before you begin to read new text, new topic or new
material. Write on the paper all the things that you have learnt the
previous day on the same subject. Ask questions on what you read and
answer them. No need to be clean, concise or correct, just write.
Write whatever you remember. Imagine the terms and get them on paper.
Run through the topics one by one.

Well that's it, once this is done, turn the paper down and get back to
study the new stuff.

There are 3 distinct advantage of this technique.

1. You poke your mind and exercise it to get active and retrive the
information it received earlier. Just by remembering and writing it
out you strengthen the ties.

2. This exercise at the start of your study session sets up the mood
to study further, to learn more and to dive deep.

3. The old things and topics that you bring forward by means of that
paper creates additional pegs that you can hook the new informations in.


Well I believe if you follow just this method, you are well ahead in
your studies. Try it!

Everything else is just noise

"Everything else is just noise"

Read this beautiful quote and immediately loved it. Be worried and
concerned about your studies when you are in aesi. Read study and
write; that's what I want to tell you. Everything else is just noise.
Noise!!!


Learning a software, training, experiments with practical are all none
if you don't pass papers. Its no big deal if you are stuck in clearing
the papers. And for that you have to read, write and study.

Study hard and play. Don't worry about the distractions. Keep your
focus on passing AeSI with good marks and every thing else will follow.


So focus.

Two software skills to choose by an AeSI aerospace graduate

Here I am again telling you which software you can take up for your
skills and professional developments.

The tools I will suggest are not the onces I had enough experience nor
are those that I would have thought of when starting out just out of
AeSI. They are the suggestions from the experience and environment
that I have been for the last couple of years.

If you are interested in CAD, then shun catia, overlook solidworks,
take up unigraphics. That's the future. That's what aerospace industry
is using.

If you are interested in analysis, make ANSYS you vehicle of choice.
Start tinkering, and learning about it from today.

Well that's it nothing fancy. Not many choices, but just two specific
softwares to choose from.

Choose one today and begin devoting one hour each day on it for the
next two year, and you will not have to worry about job or career
ever! That's a promise.

What's the secret of taking a great photograph?

What's the secret of taking a great photograph and why knowing that
will help you as an AeSI student and graduate.

The secret of getting a good photograph is to take a lot of them. The
more you take, the more are your chances of getting that perfect shot.
For some it will come at the 10th shot, or the 100th or beyond.

But what is important is taking shots. Same way the best way to learn
and perfect any cae software like catia, nastran, ansys etc is take a
lot of shot at them. Do them again and again and again and again.

Repeat a truss analysis, repeat a compresseor blade model. Don't just
stop but take action and take as many shot as you can.

The beauty about the digital camera is that you don't have to worry
about the reel, the developing. Same way, the cad and analysis tools
help you in giving you a virtual model or products, thus enabling you
to manipulate it to your hearts content.

So with minimum cost and fuss, you learn a lot. So when doing the next
session in ansys or catia, do become a photographer and take lots of
shots.

Quit waiting for the right answer?

Are you waiting for the right answer? Well If you are then that's a
waste of time, my friend. In truth you will never ever get the right
answer.

The correct choice or the right answer is an illusion.

The faster you understand this the better you will be.

I have passed section A, which stream to choose for section B? There's
no right answer to it.

I passed AeSI, but I don't have 60%. Should I continue on or redo the
exams? There's no correct choice.

Should I go for higher studies or do I take a job? There's no right
answer.

Which field should I go, design or analysis? There's no right answer.

Which software tool should I take up, catia or solidworks? There's no
right answer!

At one point or the other you will face this or similar questions in
your jouney of AeSI, they will creep in. You will ponder over them,
ask many people, contact seniors for advice and each answer will
settle you deep into the question and you will search for the right
answer.

But let me tell you, there's no right answer. Do what you feel that is
correct at that time. That's the important thing. Staying in the
vortex of your questions won't take you anywhere. Just listen to heart
and follow it.

That's the best you can do instead of waiting for the right answer!

What are your thoughts on this, do comment.

Getting into turbulence

Since January to this time of the year, I have fairly be in a laminar
flow, so to say, in terms of posting to this blog.

From Internet connection problems, to a blackout laptop. From being
with no projects to work, to teaming with projects, I have updated the
site consistently. But now in October, I have a lot of travel in my
calendar and Posting will enter the world of turbulence. I expect few
delays, hiccups.

So this post is just a warning that posting to the blog might be
irregular in October. . Though I am making plans to mitigate those.
But time will tell.

Cheers.

Ps: For those who do remember the Ebook I promised. Well as my laptop
tanked, so it stalled the launch of that Ebook. Maybe I'll link and
upload the free after aesi- career guide after aesi ebook in October.
Wait and watch.

By the way, if you are filling adventurous, please visit http://my-aesi.blogspot.com

Three steps to sucessful career

Recently I read an article titled three steps to a joke and that let
me wonder on the question of what are steps for a successful career.

Well here's my answer?

Communication skills.
Technical skills aside, single most important skill that one should
have, acquire or cultivate is communication skills. This is the one
skill that will enable you to progress in your career. Technical
skills gives you authority but it's the communication skills that
spread the infuence and this is first skill that you must develop
before you move on to any another.

Curiosity and experiment.
Being curious, being open to experimenting. Testing your theory is the
next skill that you should cultivate. Being good at technical skill
and just knowing it bare minimum won't be enough. Be curious, ask
questions. Answer them with experiments. It's more than a skill but an
attitude that you need to cultivate!

Solve problems.
What good is an atiitude or skill if you aren't solving problems.
Solve problems, yours or of peoples around you. This is the only and
THE only way to accelerate your skills. Problems are the grindstones
of honing your skills, technical or otherwise. So look from problems,
annoyance, in and around yourself and solve them.


As I said, these are my 3 steps to a successful career. What's yours?
I am curious. Pitch in your comments.

Put the bloody weapon down!

Yes that's what an outsider from aesi will tell you.

Put the bloody weapon down?

If you don't respect your degree, your education and you talk about it
with that attitude, you are carrying a weapon pointed towards
yourself, towards your progress, and towards your career!!

This comes off when you are in an interview or when you are explaining
your education. If you don't respect the hard work you did, you are
holding a weapon in the path of your sucess. So put the bloody weapon
down!

Respect your degree. Know you are among the best!

How to answer interview questions?

Paint a picture.

In his first interview he explined moment of inertia anything better
than the interviewer knew and he got selected. In his next interview
he floored the interviewers by his explaintion of optimization, same
way in an another interview he wowed the interviers by his insight on
working of gas turbines.

This is a real friend of mine and who has done great in all the three
interviews I mentioned.

His technique is simple, for any definition type question they ask on
general theory, paint a picture. Explain it in such a way that after
the answer, the person getting the answer would have a crystal clear
picture of the concept in his mind.

Whenever I saw him prepare, I noticed how he emphasized his
preparation on the basic concepts. He shunned the usual definitions
and went deep to understand what it is and then tried explaining that
concept.

So what can one learn from my friend.

Be clear of what you have studied and be prepared to explain the topic
such that it really shows that you know the subject.

For practise you can use the 101 aerospace questions that this blog
has to apply this concept.

Good luck

Cinema, funcity and NAL training! - What's the connection?

You don't buy a ticket for cinema and sleep inside. You don't go to
wonderla or fun city and just sit outside.

You go there to enjoy, to have the experience. So why is it different
for the training?

I see lot of aesi graduates and students attending training in NAL,ADA
etc, and just doing that!

They show lot of initiative, courage and creativity to get in, but
once they are in, they just sleep or sit outside!

Why?

Training is like a theme park, where you choose the rides and
experiences you want. No one will handfeed you, or give you tailor
made experience in catia or any other tool, you have to find the
opportunities and learn.

Once you are in, resolve to get the correct technical exposure.
Surround yourself with books, people and substances that lifts you
towards your career goals. Otherwise training will be just like the
experience of a guy who buys a ticket to a movie and sleep during it.

What do you think? Let's discuss....

7 questions that you should answer about your first job

Here's 7 questions you need to answer yourself regarding your first job.

1. Is this the job that I really want?
2. Whom will I report? Is he/she known for his work?
3. Where does this job fit in my career?
4. What are my three quantitative goals for this job?
5. If I am not paid, will I do this work?
6. What really made them select me?
7. Am I really happy with the job offer?

From my experience, if you have got a job offer be it your first or
one of the many then these are the questions you need to answer
yourself to gain clarity.

Take a paper or a word processor and answer these questions. More
clarity and sense will be the outcome!

Cheers.

What can we learn from my collegue at work?

A collegue of mine is complaining me everyday that he is stuck, he is
doing uninspiring work? He is not learning anything new!

I don't know about him but I see an opportunity there. I see time that
he can utilize to learn whatever he wants to but all he does the same
repeatative job at the same slow pace.

He is using excel and is doing the same kind of work for a year now
but he is poor in excel, by now he would have been fluent in that tool
but since excel is everywhere he disregards it. Shuns it. Hates it.

He is ignorant of simple if formula and of simple techniques of excel.

If this is attitude he approaches his work he will remain in the same
rut till he quits.

Its not what you do that will teach you but how you do something?
Opportunities don't come to ideal work, it springs from the laps of
challenging work.

So this is what I suggested him.
1. Automate your repeatative work.
2. Do the work at a faster pace.
3. Utilize the remaining time doing small experiments in excel.
4. Read more about the tool you are using.
5. Aim to be an expert in it.
6. No tool is unimportant.
7. Your value is not it the number of tools you know but in the things
you can do with the tools you know.

I wish I could do some more for him. But I know he is the one who has
to walk. All we, as external person, can do is point him the right way.

As always I am curious what do you think?

Don't cruise climb up!!

Faliure is a good teacher. If you are not failing, not facing problems
in your projects and tasks them be sure you are not improving.

Don't be complacent. Don't be stagnant. Don't be static.

Failing on a daily basis is needed to learn. So experiment, fail and
again rise up.

Whatever you are doing in your life now, resolve to fail everyday.
Unless you are doing so you are just cruising not climbing up!!

Be a sponge.

In your first job, in training and whenever you are learning something
new be a sponge. Soak as much info as you can.

The bigger the sponge you are the faster you will learn, grasp and
comprehend the new material.

So be a sponge.

But only being a sponge never helps. What use is a sponge in an arid
sandy desert?

Sponge is useful when it is in an environment that's abandant with
soaking material.

So be a sponge and immerse yourself in all the materials of the things
you are learning.

1. Be with people who know the thing you want to learn.
2. Visit wikipedia and learn all about the subjects.
3. Subscribe to blog from those areas.
4. Read tutorials, articles, and post related to the topic of your
interest.

As you see, to accelerate your learning you need to be a sponge and
get into an environment that presents you opportunity to soak. If any
of the two is missing, you are pressing the brakes instead of the
acceleration.

Teach yourself methodlogies and process not the tools

Teach yourself methodlogies and process not the TOOLS!

When learning a new software tool, be it a CAD software or a analysis
tool, keep reminding yourself of this. Learn the methodology and
process not the tool. Learn why something is happening than how.

Delve deeper in different boundary conditions and domains than just
blindly applying them repeatedly on models. Understand the difference
and significance of different elements before choosing one over the
other. Understand the different ways of loft before applying it in a
cad model.

It's very easy to loose sight of wood for the trees. But keep your
mind alert and know what you are doing and do what you know. Anything
else is just wasting time and resource.

Why riding on road really works?

A few days back I made a post regarding how riding on a road improves
your driving than practising it in open grounds. I used the same
analogy to learning catia, solidworks, unigraphics, ansys , and
nastran etc.

I laid out steps that one can take so that even without a real life
example, one can accelerate one's learning of a cad or cae tool.

Here in this post I will discuss why it works?

Why riding on real roads really work?

1. It puts you out of the leisure zone.
2. It presents you unexpected turns.
3. It puts you on the real test.
4. It focuses you not on results but on the process.
5. It presents the situation where you need to apply your knowledge at
every turn.


Same applies for learning a tool. Be it a cad tool like catia,
solidworks or unigraphics or be it an analysis software like ansys,
nastran, fluent etc.

The main advantage is that you disregard the nonsense, superficial
stuff and do the things that's essential and important.

Changing gears at every corner is a skill that one learns when he is
on a real road facing real traffic, same way, while doing a software
with real world examples one learns of different constraints that
never appears while practising a tutorial. And this constraints and
limitations enables you to think and solve the assignments in creative
ways.

So next time you sit to learn a software tool, shun the off repeated
tutorial. Challenge yourself to make something that you can share with
others. Challenge yourself to make something that others will find
usefull. And begin making it. This will teach you 100 times more than
following the steps of 100 tutorials!!

Try it!

How to give a great start to a new semester? - 3 tips

New semester have began for many of the AeSI students. It's the time
when classes start and we all fall in the grove of going to classes
and tutions. Life falls into a routine and it's becomes easy to miss
out the right way to begin a new semester.

So here I will present you three ways (although all are related) to
begin the new semester that lays a strong foundation.

1. Cut out your study hours.
This is the start of the semester. Don't put too much time pressure on
yourself. It's the time when you have the leisure of time. So utilize
it on other things than taking notes more than needed, and studying
more than required!

Do the minimal study, read ahead what will be taught in the class and
the tution and be attentive in classes. Apart from that don't study.

2. Reflect.
Instead spend time reflecting on the things you are learning than
mugging up formulaes and data for the exams! Reflect on whatever is
taught in the class, imagine the concepts introduced, discuss or
connect what you learnt today with what you already know.

This is the time when you want to build the foundation of your study,
so shun making notes, mugging, and solving hundreds of numericals.
This will come latter in the semester, right now lay a strong
foundation with the concepts.

3. Use pen paper and drawing.
Use pen and paper. Draw, imagine and relate the stuff you are
learning. Take imaginary classes of the stuff you are learning. Teach
what you have understood, question what you haven't!

This is how the begining of you new study should commence.

As always, I am curious what do you think about this? Are you
following a nobel way? Do comment.

The Pareto principle and AeSI Results

The Pareto principle (also known as the 80-20 rule) states that, for many events, roughly 80% of the effects come from 20% of the causes. And this is true for AeSI's AMAeSI results too.

As I saw the June 2009 results of section A of AeSI, I found that close to 80% pass outs were from roughly 20% of the subjects. As I plotted the results on a pareto plot, whose purpose is to highlight the most important among set of factors, I found the subjects of basic electronics, fluid mechanics and strength of materials taking the lead, while Electrical Engineering, Introduction to Aeronautics, microprocessor and software engineering and applied mathematics lag behind and having the lowest passing percentage this semester.

So what does this mean? what does it point to? what does it show? Which are the subjects that you should concentrate?

Use this knowledge to improve your results. Work hard on the easy subjects to get the highest marks and in the difficult once work hard to understand the underlying concepts. Practise more for the hard subjects. allocate more time to them, discuss these subjects more.


The Pareto Principle also applies to a variety of more mundane matters: one might guess approximately that we wear our 20% most favoured clothes about 80% of the time, perhaps we spend 80% of the time with 20% of our acquaintances, etc.

A quick tip to get your resume noticed.

Here's a quick tip to get your resume noticed and net an interview
request based on it.


I receive updates from naukri.com every other day and they are fairly
accurate in reflecting the type of work I am doing and interested in.


But lately I am seeing a surge of opportunities seeking engineers for
aerospace related work and each of them mentions gas turbines in the
description.


So to improve your chances to get an interview request, update your
resume by adding the term gas turbines in your resume. I am sure your
resume will filter through and fall into the radar of the requirements.

I am not suggesting you to lie and just add the term but I am
suggesting you to add the term because if you have done aesi, you
can't escape studying them so you already know something about it. Now
is the time to fish an interview out if it.

Good luck!!

Whatever stage of life you are in, be it a student just starting out,

will clear the mist and give you more clarity.

Riding bike and learning catia what's the connection?

Until you ride bikes on real road, you won't learn it. It's 100% true
for learning to drive a motorbike. And more so for all the software
tools.

Until and unless you are working on a real project you won't learn the
tool. You may know how to use it but driving on the highway, with real
traffic is the place which will hone your skills as a driver and in
the same way on a tool.

But tutorials is what I have, I hear you say. Well then create some
mini challenges. Challenges to produce something worth sharing. Here's
few idea for anyone learning a cad (catia, solidworks, unigraphics
etc) program.

1. Select a place in your house, let's say the bathroom and create all
the bathroom assessories that you see in it in your chosen cad
program. Design from start to finish and present 2d drawing just ready
to be manufactured. Design with an intention of sharing all your model
and cad drawing sheets with the world. Post them online. Let that be
the real project you are working for.

2. Design a bicycle from scratch. Measure one and assemble a whole
unit in your chosen cad program. Make drawing sheets which enables
someone with the drawing to built the bicycle from ground up.

Well I can go on but I will stop here and let you decide how you want
to create your own challenge.

The key thing in this whole exercise is your commitment to share your
results. When you design and cad model with that intention, you will
be in the very state of mind that actual designers are. It's just like
riding on a real road.

In my next post, I will discuss why this method works and things to
remember while doing this kind of exercises.

FORTRAN IS THE COMPUTING LANGUAGE OF CHOICE

The first time I Used FORTRAN I hated the language, coming from the background and knowledge of C, I had hard time in following the rigid column rules of FORTRAN 77. But now as I continue to use it for the last 4 years, I have completely fallen in love with this language.


So here's a brief history of the language that essentially began the IT revolution.

"
The development of FORTRAN I
----------------------------
The first FORTRAN compiler was a milestone in the history of computing,
at that time computers had very small memories (on the order of 15KB,
it was common then to count memory capacities in bits), they were slow
and had very primitive operating systems (if they had them at all).
At those days it seemed that the only practical way is to program in
assembly language.

The pioneers of FORTRAN didn't invent the idea of writing programs in a
High Level Language (HLL) and compiling the source code to object code
with an optimizing compiler, but they produced the first successful HLL.
They designed an HLL that is still widely used, and an optimizing compiler
that produced very efficient code, in fact the FORTRAN I compiler held
the record for optimizing code for 20 years!

This wonderful first FORTRAN compiler was designed and written from
scratch in 1954-57 by an IBM team lead by John W. Backus and staffed with
super-programmers like Sheldon F. Best, Harlan Herrick, Peter Sheridan,
Roy Nutt, Robert Nelson, Irving Ziller, Richard Goldberg, Lois Haibt
and David Sayre. By the way, Backus was also system co-designer of the
computer that run the first compiler, the IBM 704.

The new invention caught quickly, no wonder, programs computing nuclear
power reactor parameters took now hours instead of weeks to write, and
required much less programming skill. Another great advantage of the new
invention was that programs now became portable. Fortran won the battle
against Assembly language, the first in a series of battles to come,
and was adopted by the scientific and military communities and used
extensively in the Space Program and military projects.

The phenomenal success of the FORTRAN I team, can be attributed in part
to the friendly non-authoritative group climate. Another factor may be
that IBM management had the sense to shelter and protect the group,
even though the project took much more time than was first anticipated.

Two Professional development programs in and after AeSI

Two programs that you should keep an eye on for your professional
development in and after AeSI.

One is iisc's short term proficiency courses that are conducted twice
a year. The courses are on fem, project management and many other cfd,
and engineering related topics. The courses mostly deal with theory
and strengthing concepts!!

Second short term courses are from MSRSAS. They come up once a year
and are more inclined towards tools like Catia, unigraphics, ansys,
nastran, fluent etc. !!

Right now my Internet access is next to nothing, so I won't be able to
offer any direct link to both of this. But google it, google still is
as good as it was in finding things. :)


Well this two were the one I knew and had some practical knowledge
about. If you know something else please do include them in comnents!!

What every aerospace job requirement is looking for?

See any aerospace job requirement on different job sites or the onces
posted in ouraesi, aesi yahoo group or at aesiaa, hand calculation is
the one thing that jumps out of them.

As I have previously noted hand calculation is what companies are
looking for and this is were your aesi studies will come in handy.

So after you graduate, don't just concentrate on your software skills
but take a hard took at the hand calculations. You should be able to
solve truss on paper before you analyze it in ansys or nastran, you
should be able to design a shaft of required strength on paper before
designing it in catia or solidworks.

Don't neglect hand calculation over softwares.

Don't let your engines ideal!!

Don't throw a spanner into the cogs of your study life. Start
immediately. Don't postpone your studies till the last two months
before AeSI exams, instead start today.

Doing one hour of study per day from today is much better and
effective than studying for 16 hours a day in the last month before
the amaesi exams!!

So don't let your engines ideal, start now and be consistent. You will
be in a much better shape during the exams!!

Hurray AeSI Alumni Association official now!

Hurray AeSIAA is official now. What is aesiaa? It's AeSI's official
alumni association. As President Mr. Rituraj has stated in a recent
mail, it's a whole new begining!!

Answer this! What makes IIT's? It's their alumni's!!

Likewise AeSI alumni Association aims for being the face of AeSI. It
aims for professional development of graduates of AeSI. It's aims to
strenghen AeSI's engineers market value.

So your first pit stop after graduating AeSI should be AeSIAA!!

3. Be ready to explain the concepts in general terms not the
definitions.
4. Know your resume like the back of your hand.
5. Talk slowly.
6. Explain and paint a picture when explaing a concept.

I know a friend of mine who is expert at explaining stuff. And he uses
this approach in all the interviews.

Importance of First Class Degree in Aerospace Job market - help me answer this question

Recently I got a mail from someone who has graduated from AeSI this semester. We had the following discussions on email. Now I want your help on this. So readers of this blog please pitch in and have your say to what he should do or not do?


Please read the whole of the discussion and chip in your comment at http://my-aesi.blogspot.com/

Hello Sir,

This result brought a new spark in my life as I 'finally' cleared my BE from AeSI (in Propulsion). Although I find this good news surrounded by mist.. I cleared my degree with 58%.
My confusion is, will 58% pose obstructions in growth of my career? Is it difficult to grab a good first job with less than 60%? Also, as of now I am not planning for post graduation.

Since you really hold good knowledge of Indian Aerospace job market.. I keenly seek your advice on this.
What should I do, should I get my degree in current status or should I wait & go for improvement (I'll have to take at least 2 subjects to make up for deficit). Although I am not very interested in delaying my degree by another 6 months, but nothing stands taller than requirements which are necessary for a good career.

I hope I was able to express myself well, plz let me know if there's anything more you need to know to advice me on this.
Waiting for your response...

Thanks & Regards


My reply.....

Hi

Congrats on Becoming an engineer!! Well the choices you are facing are similar to what I faced when I received my final mark sheet.

So what should you do? Frankly I don't know! Nor will anyone else know. It's your decision that you have to take. But here are some points that I can state to help you decide.

1. 60% is absolutely necessary if you want government job. They still insist on it. Rules are bend now on then but not always.

2. Very very few people get a job just after graduating. Even if you are above 60% you might have to wait for couple of months to get a job.

3. Skills are more important than the degree. If you have the skills there is no way people can restrict you in any company.

4. There are lot of AeSI graduates in every aerospace organisation in India so AeSI folks are all accepted in companies. Remove a shadow of doubt that AeSI and low percentage marks can hinder you.


5. Yes having percentage will open more options but it's the skills that will help you soar in your career. If you have the skills. You will get a job in days.

As I see it from this side.

A career is like a hot air balloon. Your degree gives you the permit to fly, and the percentage is just the volume of the balloon. What really matters is the hot air. If you can pump enough of it , no one can stop your balloon to reach the sky. This hot air is your abilities, your skills, your initiative.

So its up to you now, do you want increase the volume of your balloon or pump it up with hot air to begin your journey as an engineer.

Good luck!!

Hello Sir,

Thanks for your reply (specially when you wrote all this from your mobile) :)

I do understand that skills hold a very important position but fear from situation when at few places people won't even agree to look at my CV as I am ineligible according to their rules!!

"1. 60% is absolutely necessary if you want government job. They still insist on it. Rules are bend now on then but not always."
- What % does govt jobs constitute among all? Can a person be still in a comfortable position for fetching a job if he is not eligible to apply to govt jobs due to 60% rule. I don't have much idea on this. Please comment...

Also, are private firms not much concerned about this fact or is it like they tend to ignore it if otherwise you posses a good profile?

What did you decide at your time? :) Where are you working these days?

There's one more thing sir, In the job market, is there really a difference in jobs for Propulsion or Aerodynamics engineer? I mean like this job is for Aero & this is for Prop. Should a person just grab whatever is coming his way, prop based or aero based (sometimes getting a job becomes more important than field of interest)?

I hope I am not troubling you much with my never ending questions... :)

Thanks & regards


I know I have lot of readers who have lot to say on this topic, with this blog post, I want to invite all the past and present AeSI graduates to share their experience and advice with him. So now its your turn, come forward and have your say. Write in your comment at http://my-aesi.blogspot.com
